Mal, looking back at my post, I didn't say anywhere that "I have limited
knowledge".  Perhaps you are confusing my post with one from someone else?  

Confusion and memory issues are common traits in the elderly, so I wouldn't
worry about it too much if I were you.   

As for "opinions" they too are rather commonplace in amateur radio with most
operators holding dear several of them.

I'm pleased to hear of your excellent QSO results, good stuff

Keep at it


With best regards
 
 
Jim

James if you were a competent CW operator you would think different, like 
you say you have limited knowledge.
WSPR beacons ARE a LAZY APPROACH no skills required and vy limited regarding

propagation predictions.
I had two nice solid QSO'S two nights ago on CW/QRS to Russia and Romania. I

did not need WSPR assistance. Any experienced CW operator can check a band 
and give an opinion about propagation in real time, then proceed to make a 
QSO.
